When it comes to osseointegration, treatment success with implants that have a moderately rough, anodized surface is well proven.1,2 Professor Tomas Albrektsson, involved in dental implantology since the very beginning, is a prominent expert in dental implant surfaces and was a keen observer when Nobel Biocare first introduced the moderately rough, anodized TiUnite surface back in 2000. Fast-forward to 2017, and he co-authored what is believed to be the largest ever systematic review and meta-analysis of a single implant brand, which confirmed high efficacy of Nobel Biocare implants with the TiUnite implant surface.2
Implant surface video presentation
With the recent introduction of the TiUltra implant surface and Xeal abutment surface, in this presentation, Prof. Albrektsson summarizes the evolution in implant surface knowledge and research. He explains clinical and scientific evidence relating to several implant surfaces, and casts some light onto why implant anodization has been developed further by Nobel Biocare.
Key topics include:
- Comparison of implant surfaces
- Important implant surface characteristics
- How implant surfaces have been tailored to meet biological needs, particularly regarding surface roughness, porosity/morphology and surface chemistry.
- How treatment success with anodized implants has been clinically proven*
- Summary of the TiUltra anodized implant surface

As described in this presentation, anodization allows for precise tailoring of surface features such as surface chemistry and topography.3,4 TiUltra is an ultra-hydrophilic, multi-zone implant surface featuring a gradual change in topography, from a minimally rough non-porous nanostructured implant collar to a moderately rough porous apex.3 Xeal abutments have also been introduced, featuring a smooth, non-porous, nanostructured anodized surface.5 The Xeal surface chemistry and topography have been designed to promote soft tissue attachment.4
Xeal and TiUltra not available in all markets.
